[Vince] teaches an Embedded Systems class at the University of Maine, and some of his students were working on video games for their finals. He decided to “test the hardware” that the students were using by putting two 8×8 displays, one 4×7 segment display, and a Wii Nunchuck on the I2C bus. He then wrote a version of Tetris that accepts trigger presses and accelerometer input for control. Judging by the video (embedded after the break), the Raspberry Pi runs the game without issue. The bus is, of course, more than capable of handling everything.
Unfortunately, [Vincent] had some trouble getting the controls just right. Sometimes dropping a piece can cause the next to drop too quickly, and the accelerometer control seems a bit too sensitive. We imagine using the joystick for rotation and adding some strategic pauses in the game could help. He graciously released the source code for the project, so maybe we’ll see some embracing and extending in the near future.
